A one-and-a-quarter-dimensional transport code for field-reversed configuration studies: A user's guide for CFRX

Abstract

A one-and-a-quarter-dimensional transport code, which includes radiai as well as some two-dimensional effects for field-reversed configurations, is described. The set of transport equations is transformed to a set of new independent and dependent variables and is solved as a coupled mitialboundary value problem. The code simulation includes both the closed and open field regions. The axial effects incorporated include global axial force balance, axial losses in the open field region, and flux surface averaging over the closed field region. Input, output, and structure of the code are described in detail. A typical example of the code results is also given.

Electron energy confinement in field reversed configuration plasmas

“…While anomalous, the inferred Xxe remains four orders of magnitude smaller than the classical value along magnetic field lines, xie = 3.2 kT^Jn^. The conductivity anomaly factor from the simple dimensional analysis for the 3 mtorr case has been verified by a detailed simulation with the 1 X A -dimensional fluid transport code CFRX [16,17]. Time dependent magnetic field, plasma density, and electron and ion temperature profiles are computed as a function of the magnetic flux yp.…”
